Application led September 9, 1921. Serial No. 499,476.

' To all who/122er may con cern Be it known that l, Henson M. Jnnovrn, acitizen of the United States of America, and a resident of Davenport,county of `Scott., and State of Iowa, have invented certain new anduseful improvements in Ice-Shavof which the following` is a full andclear specification.

The object of this invention is to provide a simple. inexpensiveapparatus for reducins ice tosmall particles by the sh aving method vandthe invention consists of certain novel features of constructionhereinafter described and Claimed.

In the drawing- Fig. 1 is a side elevation of my machine;

Fig. 2 is a front elevation thereof;

Fig. 3 isa vertical section of the machine;

Figs. l to 7, inclusive, are views of details hereinafter described.

Referring to the drawi reference-numerals, 10 de upon which is supporteda casing 11 consisting of two circular halves one of which. is bolted tothe base and the other is secured to the former by bolts 12. W'ithinthis casing is mounted to rotate a disk 18, which is aiiixed to a shaftlll journaled in bosses formed integrally with the walls of the casingmembers and provided at one end with a hand-wheel 15 for rotating it, itbeing obvious, however, that a small electric motor or other power maybe used instead of this hand-wheel, The disk is provided with a seriesof radial slots or openings, and in each one of these openings ismounted a sliavingblade, every alternate blade having serrated teeth;the plane-edged blades are designated 16, while the serrated-edgedblades are designated 17. Ars shown clearly in Figs. 5, 6 and 7, theshaving-blades are formed with bevelled cutting-edges, and theserrations or teeth on the blades 17 are formed by grooving the bladetransversely entirely across its underside (as indicated by theclosely-spaced lines in Fig. 6), said grooves cutting through the thinbevelled edges of the blades and thereby forming the teeth.

At the rear side of the knife-casing is arranged a hopper 18 adapted toreceive the lumps of ice to be shaved. FThis hopper is desirably castintegral with the rear plate of the casing 11 and is located at the leftof the center of rotation of the knife-disk. its botannexed by tom wall19 curves backwardly and upfor the ice-lumps. The front sideof thehopper opens into the casing 11 its full height, so that the ice-lumpsmay be pressed directly against the `downwardly-moving edges of theyknife-bla .lcs, to thus shave oil the ice and deliver it through theslots in the disk into achute 2O integral with the front-plate of thecasing 11, this chute widening downwardlyfto an open lowerend, where theshaved ice will be delivered. a suitable receptacle being arranged`below the top plate of the base 10 to receive the shaved ice.

To press the ice-lumps against the shaving-knives and thus automaticallyfeed the lumps to the knives, 1 arrange a gravityfecd device consistingof a head-plate 21 pivoted at 22 on the upper edges of the sidewallsofthe hopper 18, at a point near the casing 11, This pressure-head 21 isapproximately the width of the hopper 18 and, by reason of the fact thatit is pivoted near the casing, at 22, it tends to normally swing towardthe casing. An arm 22 is rigidly aflined adjacent. to the lower edge ofthe pressure-plate 21 for the urpose of conveniently lifting it out oftie hopper to replenish the ice-supply therein. This arm is enlargednear its lower end at 28 to form a weight which is sufficiently heavy toforce the pressure-plate 21 against the ice with the desired pressure,thereby eliminating t-he necessity of manually forcing the ice againstthe knives. The arm being rigidly affixed to the plate, it supports theweight clear of the bottom wall 19 and thus prevents frictionalresistance. To prevent the pressureplate contacting with the knivesafter eX- haustion of the ice, l provide the armv22 with a stop-lug 24,which is so located as to strike against the rear edge of the hopper 18when said pressure-plate nears the knives.

at will be observed that my apparatus is simple and is capable of beinginexpensively made, and, further, that the feeding of t-he ice to theknives is accomplished without manual pressure. A further feature ofimportance is the alternate arrangement of serrated and planeshaving-knives, whereby the serrated edges score the ice ahead of eachplane-edged knife7 thereby reducing the power required for cutting theice to a minimum and making the machine very easy `to run.

It will be observed further that the casing l1 covers the cutter-wheelclosely on both sides except at the places where the delivery anddischarge chutes are located,

vand both of these are positioned wholly to one side of thedriving-shaft, which permits the shaft to be mounted in suitablebearings formed on the outside of the inner side-wall of both thedelivery and discharge chutes.

The nature and scope of the invention `having` been thus indicated andits preferred .cutter-wheel mounted to rotate in said casing, saidfeed-hopper and delivery-chute be* ing positioned directlyv opposite toeach other and entirely to one side oi the center of rotation of thecutter-wheel, whereby `both sides of the cutter-wheel are closelyconfined in the casing except at the points where the feed-hopper anddelivery-chute are positioned.

- 2. An ice-shaving machine embodying a Hat-faced cutterwheel, aguard-casing surrounding said cutter-wheel and having flat 'inner-faceswhich lie closely. adjacent tothe Hat faces of the cutter-wheel, afeed-hopper and a delivery-chute forming part of the 'facingand beinglocated on opposite sides thereof in alinement with each other andopening to said cutter-wheel, supporting bearings for the cutter-wheelformed on the side-walls and outsidevof'the feed-hopper anddelivery-chute, and Jfeeding means on the feed-hopper for automaticallyforcing the ice against the cuttin0'wheel.

3. An ice-shaving machine embodying a fiat-faced cutter-wheel providedwith alternately-arranged serrated and plain-edged ciutters to produceinely-shaved ice, a guard-casing surrounding said cutter-wheel andhaving fiat inner-faces which lie closely adjacent to the flat faces ofthe cutter-wheel7 a feed-hopper and a delivery-chute forming part of thecasing and located on opposite sides thereof in alinement with eachother and opening to the cutter-wheel wholly to one side of the axisthereof, said fiat inner` 'faces of the casing in their close relationto they cutter-wheel :forming strippers for the cutter-wheel at theedges of the casing adjacent the feed-hopper and` discharge chute toprevent the yfinely-shaved ice passing into the bodyvoiA the casing, andmeans in the eedfhopper for feeding the vice against the cutters.

In testimony whereof I hereunto affix my signature. 1
